' REISSUED This invention relates to what are known as separable fasteners and particularly to devices of this class employing detachably' coupled end I stops whereby the fastener stringers may be completely separated. thus adapting the device for use on shirts, jackets and similar articles of merchandise; and'the object ofthe invention is to -,provide means for positively latching or-retaining the slider of fasteners of the kind underjconm sideration in connection with one .part of a tietachable end stop coupling, especially when the stringers are separated so as; :to' facilitate v and insure proper recoupling of'the .end stop parts, and stringers: a further object being to provide one part of an end stop'with a pivoted hook arm or latching -member with.tenslonal means for normally supporting "saidyarm or member in operative position and in engagement with av coupling element on the slider when arranged adjacent said end stoppart: a further'object being to provide means whereby the insertion of the other of the end stop parts intothe first named part will move said member into inoperative position to release the slider; a further" object being to provide means for housing or shielding the hook arm or latch member within said end stop part; a further object being to provide s'coupling element on theslider arranged within a re-' cessed portion thereof; a still further object being to provide the end stop part and slider with relatively wide abutting surfaces to maintain alinement of said parts when coupled together, facilitating coupling and uncoupling of the end stop parts: and with these and other objects in view, the'invention consists in a device of the class and for the purposespeciiied. which is simple in construction, efllcient in use, and which is constructed as hereinafter described and claimed.

The invention is fully disclosed in the following specification. of which the accompanying 50 and showing the sliderin elevation.

Fig. 4 is a partial section on the line 0-4 of Fig. 3; and,

5s i Fig. '5 is a view similar to Fig. 2 with part of the slider shown in section showind a modifies-- In the drawing, Ihave indicated at II and II" one end portion of the tapes of the stringers of;

a separable fastener, to the adjacent beaded-r edges I2, i3 of which are attached the coupling urormer r links or scoops l4 and I5 which are adapted to be coupled and uncoupled by a sliderll movable longitudinally of the stringers, in other de'-,

vices ofthis kind. The slider is provided with'flv a finger piece-orpull i! by means of which'the same may be operated. At il' and IQJI have," I

shown reinforcing strips- .or sheets; secured to ends and adjacentedgesof' the tapes .II and H to reinforce the same, and as" the specific structure of these reinforcements fis old, no

: descriptionis necessary here.

. At II; I have shown'one part ofasdetachable end stop structure, said part'being in the form of a v U-shaped or substantially '-U -shaped body permanently secured to the part II and including a projectingbar portion 2lat one side thereof. The other side of the part 20 has a channel 22 for receiving the pin part -23of the end stop; The part 2: is secured to the beaded edge it of the stringer tape l i', it being understoodthat the bar II is secured to the corre-- sponding edge of the tape Ill.

In the construction shown in. Figs. 1 to 3-inclusive, the slider I6 is provided on one side surface, the rear surface in the construction shown,

with a projecting lug or latch element 'fl and the part 20 is recessed as seen at 25 to receive a coupling pawl or latch member 26 which is "pivoted to the part 20 on' the'pin 21, said mem-- her having an outwardly projectinghook'f portion 28' adapted to cooperate with the lug as'seen in'Fig. 3 of the drawing to couple the slider ll. with the part 20 and in supporting adjacent surfaces of the slider and part 20in abutting relation as seen at 29 in said figure. The part 2' includes an outwardly projecting hood or hellsing portion 30 arranged over the hook-shaped end 28 of the member -26 to guard and protect said member as well as to render the same substantially invisible. i i I The rear end portion of the member 26 has an inwardly offset flange 3i which extends into the spring 32 is mounted in a socket ll formed in the part 20 and :bears against the flange ll n01 j mally urge the hook and 2 0 oftheihenrberl into thejposition' indicated in Fig.3 of em-swing and said member is movable into inoperative J channel 22 of the part 20 so as to be engaged by the pin 23 when inserted in said channel. Acoil thereof. With this construction, until the pinpart 23 of the detachable end stop coupling is in proper position within the part 20, it will be im possible to operate the slider IE, or, in other words.

to disengage the slider from the part 28. Thus, it will be impossible to jam or otherwise improperly couple the fastener stringers, thereby overcoming a great objectionable feature and difliculty with detachable end stops for separable fasteners as heretofore commonly employed.

In Fig. 5 of the drawing, I have shown a slight modification which consists primarily in changing the structure of the slider I8a by providing a recess 34 in the inner end of the rear wall or plate thereof, and in arranging the projection 24a in said recess rather than as a protruding body upon the outer surface of the slider as in Figs. 1 to3 inclusive. Thus, with this arrangement of the coupling 24a, the member 26 including the hook end 28 thereof will simply have a slighter offset than with the structure shown in the other figures. In like manner, the hood 30 will not protrude on the part 20 to such a great degree as shown in the other figures. Otherwise, the structure and method of operation of the respective parts will be the same as that shown in Figs. 1 to 3 inclusive. In this connection, it will be understood that the part 20 may be constructed in any desired manner and of any suitable design consistent with or suitable for use with sliders of different constructions. In like manner, the form and construction of the coupling or latching means employed on the respective parts may be modified or changed to be consistent with the structural changes of said parts.

The fundamental principle of my invention resides in the provision of interengaging coupling or latching elements brought into operative engagement with each other when the slider is arranged adjacent the end stop and when one part of the end stop is detached in the'separation of the stringers and in maintaining the slider and said first named end stop part against relative movement until the second named end stop part has been recoupled and brought into properly alined position, at which time, the coupling means is released, facilitating movement of the slider in coupling the stringer links. In this connection, it is desirable to employ a coupling or latching means which is positive in operation and wherein a pull upon the slider will not permit forcible detachment of the slider from the end stop, it being understood that the strength of this coupling depends entirely upon the strength of the parts, but no normal manual pull or strain would be sufficient to break the coupling parts employed. In othenwords, the couplings 24-28 form a rigid non-yielding connection between the end stop and theslider, the coupling elements 24-28 being composed of rigid or firm material and the element 26-28 forming in fact a solid coupling link between its pivot 27 and the element 24.

In these respects, the structure hereindisclosed differentiates from the structure disclosed in a companion application Serial Number 106,961, filed of equal date herewith as well as from the structure disclosed in an earlier application, Serial Number 78,604, filed by me May 8, 1936.

From a consideration of Figs. 3 and 4 of the drawing, it will also be apparent that the projecting hood portion 30 which covers the hook end 28 of the link or latch member 28 is provided with a side wall portion 30a which is adapted to engage the lug 24 to prevent lateral displacement of the slider, especially when the pin 23 is detached, the wall 30a preventing movement of the slider in one transverse direction and the bar 2| preventing movement in the opposite direction. With this construction, the proper alinement of the lug 24 with the hook end 28 is assured and maintained. Normally. the lug 24 is arranged in spaced relation to the hook end 28, and by providing this spacing or clearance, the looking or latching oi the slider with the end stop may be assured, even though the slider is disposed in spaced relation to the end stop. It is also preferred that the pin part 23 be provided with a recessed inner side 28a. intermediate the ends thereof so as to provide a freer passage of the pin part through the curved socket of the slider in the operation of coupling and uncoupling the stringers.
